I-39 truck parking in numbers
I-39 has 11 public truck parking sites in the federal inventory, with 384 truck spaces across 2 states. That is an average of 35 spaces per site, against a national median of 15 for all public sites, so the sites on this route are larger than typical.
The most spaces are in Wisconsin (300, 78 percent of the route), then Illinois (84). The fewest are in Illinois, with 84 at 2 sites.
The largest site is Rest Area #11 in Wisconsin, at mile 113, with 68 truck spaces.
The longest stretch between two listed public sites in the same direction is in Wisconsin: about 23 miles eastbound, between mile 145 and mile 168. Private truck stops may fill part of that gap; plan the last stop of the day before you reach it.
These are capacities from the Bureau of Transportation Statistics inventory, not live availability, and private truck stops are not included. The hours of service guide explains why the 14-hour window, not the 11 hours of driving, decides where you need a space, and truck parking by state compares I-39 with the other interstates.
